Scan a QR code, tap a few buttons and the money moves instantly.

There is no card machine, no cash, and - most importantly - for the user, no visible fee. That may be about to change. India has paved the way, external for banks and payment companies to charge merchants a fee on UPI transactions, potentially ending a decade-long experiment in free digital payments.

Economic Details

The government has yet to decide the rate or exactly where it will apply, but proposals under discussion include a merchant discount rate (MDR) of 0. 5% - a small fee paid by a business to the banks and payment companies that process its UPI payments - on larger transactions at big businesses. The government says, external consumers and person-to-person UPI payments will remain free.

If merchant fees are introduced, they will apply only to some transactions above a set threshold, at a nominal rate, meaning most UPI payments will remain free. The question is whether putting a price on UPI could weaken the network that made it such a success. The stakes are enormous.

Launched in 2016, UPI has grown into one of the world's biggest real-time payment networks.

Analyst Views

87 trillion rupees ($313. Fintech apps such as PhonePe and Google Pay account for most UPI payments. In the financial year just ended, the figure was about 241.

6 billion transactions - almost 12,000 times the volume in UPI's first full year. More than 550 million people now use it, external, and the system is now available in some form for payments in 11 countries outside India. UPI is not merely big.

Its design is unusual. Rather than building a closed system around a single dominant app, India created common digital plumbing on which competing companies could operate. Google Pay and PhonePe can fight fiercely for customers while still allowing their users to transact across the same network.

Financial markets are tracking the development closely as investors assess the likely impact.
